Specification of .application fried June 24, 1911i. serial No. 847,102.

j Be it known that I, VILLIAM Fnnniiioii De KON/vm, a citizen of the United States, and resident of Revere, in the county ofSuffolk and State of Massachusetts, have 'invented new and useful. 1improvements in Safety-Razors, oi' which the following is a specification.

This invention relates to safety razors, and its object is to provide a razor of novel and improved construction, whose blade may be stropped or honed withoutremoving it from the razor frame, by merely freeing the blade from its guard and clamping member and running an actuating roller over the strop or hone.

In the accompanying drawings which illustrate one embodimentJ of the invert-*1 .tion,-Figure l is a side view, partly in longitudinal section, showing the razor with the parts in position for stropping or honofthe razor with y its parts in the position shown in Fig. l and with the handle broken away; Fig. 3 is a front View with the parts in the same position; Fig. 4 is a plan View, partly in section, of the clamping member; Fig. 5 is a front view of said clamping member; Fig. (3 is af longitudinal sectional view, with the handle broken away, showing the parts assembled" andin position for use; and Fig. 7 is a detail sectional view Iot' the outer end of the handle. Y

Referring to the drawings, A represents a forked frame, and B is a hollow' handle rota- A rotatable shaft C extends between the. two branches of the foi-kA, and is journaled therein'near the endsof the arms ol' the fork. At the ends of shaft C are the pinions c, lodged within suitable recesses in the arm of the'gforlr, and meshing with pinions (Z at the ends oi" roller D. The ioller D is journalcd at the outer ends of the arms of the forl, and its periphery projects beyond the extremity of the forked iframe, in the clear, for the purpose hereinafterl explained.

fll is a blade-holder comprising a pair of jaws which grip I'the' base of the blade F. Said jaws are grooved as shown at e, e, to receive the bead or head f which extends Letters Patent. Patentes sary is, anis.

across the base of the blade. The bladeholder Eis mounted on shaft- C by means of a sleeve e which permits the shaft to turn relatively to they blade-holder,l but the bladeholder is rictionally connected to ,fthe shaft by sleeve sections et, held in position by screws c3 by which the frictional engage-2 ment of thesleeve sections may be varied. The blade 'F may be removed from the bladeholder by sliding the head f endwise out of the grooves e.

A. guard Gr, having aitextensible section g, engages the inner side of the blade F and constitutes one of the two clamping members which support and hold the blade in positionfor use. The guard G isprovided at its ends wit-,h a pair of lugs g', g', which slide in guide ways a., a., formed in the inner sides of the arms of forked frame A.; and a' screw shaft ll connected at its end with guaj'rd Gr, and extending into the hollow v'handle B, moves the guard G Jforward and ba/clrward. Said screw shaft is moved endwise by turning the handle B, which isfl interiorly threaded and cooperates with the :thread 71. on shaft H. In order to adjust the extensible guard section g relatively to the edge of the blade, the guard section 57 is made with two endgarms g which are slidably secured to guafrd G, and. may be held in adjusted position by screws g entering the ends of the guard G.

A detachable clamping member .l engages the outer side ol' the blade F and coperates with the guard to hold the blade in position for use. rl`he clamping member l is provided at each end with an inwardly turned lip or llange j forming a channel into which lits an upwardly extending` lug or finger a: on the forked frame. On the lower edge of the clamp J are ears j having beveled ends fitting the under cut shoulders (1.3 on the trame A. The clamp ,l 1s held in position against the outer side of the blade l" by the pressure exerted by the guard G when the latter is screwed forw ard into operative position. Yl'hen the razor is ready Vfor use the parts are in the po'sition lshown in l? ig. 6, with the blade Fclaiiiped between the movable guard G and]V the detachable clamp member J.
